The DBJ splits the list into five flights based on total revenue. Zayo garnered the 4th spot among Denver’s largest privately held companies with 129% growth over the last two fiscal years from $125M in 2009 to $287M in 2011.

The DBJ also reports the largest Private Companies in the Denver Area, based on fiscal year 2011 revenue; according to the DBJ’s list, Zayo is the 12th largest private company, a two-position jump from the previous year’s 14th spot.

Zayo recently closed the acquisition of AboveNet and reported the pro forma revenue of $925M and $527M of Adjusted EBITDA based on annualizing each company’s March quarterly results plus previously announced synergies of $77 million.

Non-GAAP Financial Measures

The Company provides financial measures that are not defined under generally accepted accounting principles in the United States, or GAAP, including earnings before interest, taxes, depreciation and amortization (“EBITDA”) and Adjusted EBITDA. EBITDA and Adjusted EBITDA are not measurements of our financial performance under GAAP and should not be considered in isolation or as alternatives to net income or any other performance measures derived in accordance with GAAP or as alternatives to cash flows from operating activities as measures of our liquidity.

“Adjusted EBITDA” is defined as EBITDA from continuing operations adjusted to exclude transaction costs related to acquisitions, stock-based compensation, and certain non-cash items. Management uses Adjusted EBITDA to evaluate operating performance and liquidity and this financial measure is among the primary measures used by management for planning and forecasting of future periods. The Company believes Adjusted EBITDA is especially important in a capital-intensive industry such as telecommunications. The Company further believes that the presentation of Adjusted EBITDA is relevant and useful for investors because it allows investors to view results in a manner similar to the method used by management and makes it easier to compare our results with the results of other companies that have different financing and capital structures.

Adjusted EBITDA has limitations as an analytical tool, and should not be considered in isolation from, or as a substitute for, analysis of our results as reported under GAAP. For example, Adjusted EBITDA:

· does not reflect capital expenditures, or future requirements for capital and major maintenance expenditures or contractual commitments;

· does not reflect the significant interest expense, or the cash requirements necessary to service the interest and principal payments on our debt; and

· does not reflect cash required to pay income taxes

The Company’s computation of Adjusted EBITDA may not be comparable to other similarly titled measures computed by other companies, because all companies do not calculate Adjusted EBITDA in the same fashion. Because the Company has acquired numerous entities since inception and incurred transaction costs in connection with each acquisition, has borrowed money in order to finance operations, has used capital and intangible assets in the business, and because the payment of income taxes is necessary if taxable income is generated, any measure that excludes these items has material limitations. As a result of these limitations, Adjusted EBITDA should not be considered as a measure of discretionary cash available to invest in the growth of the business or as a measure of liquidity.

A reconciliation from earnings from continuing operations during the three months ended March 31, 2012 to annualized Adjusted EBITDA for Zayo and AboveNet is as follows:

Note: The preceding unaudited pro forma financial information has been prepared giving effect to (i) the AboveNet acquisition, (ii) the offering of $1.25 billion in Senior Notes, and (iii) the entrance into a $1.62 billion Term Loan facility as if each event occurred on January 1, 2012. The pro forma adjustments reflect the Company’s preliminary estimates of the impact to the Company’s statement of operations resulting from purchase accounting adjustment. The estimated purchase accounting adjustments arise from adjusting the value of the net assets acquired to their acquisition date fair values. The determination of the fair values of the acquired assets and assumed liabilities (and the related determination of estimated lives of depreciable tangible and identifiable intangible assets) requires significant judgment. The Company has not completed its valuation analysis and calculations in sufficient detail necessary to arrive at the final estimates of the fair value of the acquired assets and liabilities along with the related impact such adjustments will have on the Company’s statement of operations.
